Configuring the Ethernet Adapter to Connect to a Wired Ethernet Device Configuring the Ethernet Adapter to Connect to a Wired Ethernet Device You can configure the Ethernet Adapter as a wireless device to connect to a wired unit, such as a computer or Ethernet printer, to your wireless network. The Ethernet Adapter can act as a wireless device, in addition to performing any one of the serial port applications discussed in the following chapters.
Network Configuration Network Configuration This section describes the network settings necessary to communicate with the Ethernet Adapter. Communicating directly with the Ethernet Adapter provides: • the ability to use the serial port applications. • the ability to ping the Ethernet Adapter. • the ability to remotely configure the Ethernet Adapter via the telnet protocol.
Network Configuration Figure 4-7: Network - Basic Tab Page 6) Enter the IP address of the gateway if your network uses a gateway (router or firewall). You need to enter the IP address of your gateway if you plan to use the Ethernet Adapter to access computers or other Ethernet Adapter units beyond your Internet router or firewall. A gateway entry is only needed for serial applications that actively connect to an IP address outside your local area network.
Chapter 5 General Serial Configuration This chapter describes the general serial settings that are required for all serial port applications. For proper operation, the settings of the Ethernet Adapter always match the settings of the device to which it is connected via the RS-232 port. There are two groups of parameters that need to be configured to accomplish this task: the UART Settings and the Flow Control Settings.
Configuration Flowchart Figure 5-1: Configuration Flowchart RoamAbout Ethernet Adapter Network Name RoamAbout Access Point Serial Port Application Baud Rate Data Bits Stop Bits Parity Bits Flow Control Network Serial Port Serial Telnet Client IP Adress Netmask Gateway Socket Listen Method Local Port Socket Connect Method Serial Line Replacement IP Adress Netmask Gateway RMP Pipe Remote IP Remote Port Command Prompt Method Wait For Keystroke Method Remote IP 5-2 General Serial Configuration LPD
UART Settings UART Settings UART (Universal Asynchronous Receiver/Transmitter) is the fundamental hardware for serial communication. It controls the speed and method of data transfer of the serial port. To configure the UART settings, perform the following steps: 1) Clicking on the Serial tab. 2) Click on the UART tab. The UART tab page is shown in Figure 5-2 with the default settings. Figure 5-2: Serial - UART Tab Page 3) Select the baud rate of your device from the pull-down menu.
UART Settings 4) Check the Data Bits setting of the device you are connecting to the Ethernet Adapter. Choose the Data Bits setting that matches the Data Bits setting of the device you are connecting to the Ethernet Adapter. Data Bits determine the number of bits used to transmit data. The possible values are 7 and 8. 5) Check the Stop Bits setting of the device you are connecting to the Ethernet Adapter.
Flow Control Flow Control Flow control is the process of adjusting the flow of data from one device to another to ensure that the receiving device can handle all of the incoming data. Flow control becomes an important factor when one of the devices is capable of transmitting data at a rate faster than the other can receive it. There are two basic types of flow control, Hardware and Software. Hardware Flow Control Hardware flow control uses dedicated signal lines to dictate transmission of data.
Flow Control Flow Control Configuration To configure the Ethernet Adapter flow control, perform the following steps: 1) Click on the Flow Control tab. Figure 5-3 shows the Flow Control tab page with the default settings. 2) Check the flow control settings of the device that you are connecting to the Ethernet Adapter. Change the Ethernet Adapter settings to match those of the connected device by clicking on the corresponding buttons. The flow control and the device settings must match.
Chapter 6 Wireless Printing This chapter describes how to configure the Ethernet Adapter to enable wireless printing to a serial printer. If you have an Ethernet printer this section does not apply. To connect to an Ethernet printer, follow the instructions to configure the Ethernet Adapter to a wired device in Chapter 4. The LPD protocol requires an operating system that supports LPD to a remote host, such as Windows.
Configuring the Ethernet Adapter to Enable Wireless Printing 6) Click on the Flow Control tab. Verify that the Flow control settings of your Ethernet Adapter match those of your printer. If the Flow Control settings do not match, there will likely be errors when printing. See your printer manual for reference on how to configure Flow Control settings in your printer. NOTE 7) Click on the Update and Reset Unit button to complete the configuration.
Appendix A Terminal Configurator This appendix describes how to use the Terminal Configurator to configure the Ethernet Adapter. The Terminal Configurator is an alternate method used to configure your Ethernet Adapter. The Terminal Configurator is a text-based configuration method. You can access the Terminal Configurator by one of the following methods: • Through direct serial connection.
Establishing a Direct Serial Connection Establishing a Direct Serial Connection This method of configuring and managing an Ethernet Adapter uses a serial cable connected from the Ethernet Adapter to a computer running terminal emulation software. To configure the Ethernet Adapter using the Hyperterminal program, perform the following steps. 1) Follow the Hardware Installation instructions numbered 1-9, in Chapter 3. 2) Connect the included serial cable into your computer’s serial port.
Establishing a Direct Serial Connection 10) Choose None for the Flow control option. NOTE The serial port settings needed for use by the Terminal Configurator will always be exactly as described here, regardless of the General Serial Settings (Chapter 5). 11) Click OK after all of the COM settings have been chosen. The next screen appears blank. 12) To bring up the local console management for the Ethernet Adapter, insert one end of something similar to a tooth pick into the “config.
Establishing a Telnet Connection Establishing a Telnet Connection This method opens a Telnet connection to the Terminal Configurator on port 23. Port 23 is the default for most Telnet programs. This only works after the Ethernet Adapter is assigned a TCP/IP address. If you need to assign the Ethernet Adapter an IP address you need to use the Ethernet Adapter Manager or the Terminal Configurator using a direct serial connection.
Using the Terminal Configurator Main Menu Overview The section provides a list of main menu selections and their functions. Resume operation This option exits Configuration. It returns the Ethernet Adapter to the settings the Ethernet Adapter had before the Configure button was pressed. Edit configuration Brings up a list of files to edit. Descriptions of the files and their contents are below.
Using the Terminal Configurator Edit Configuration Menu The Edit Configuration menu contains three selections/Config files to edit. Return to Main Menu Goes back to the previous menu selections. System Brings up the editor screen with the configuration file for options that are not communication dependent. RS-232 port (uart0) Brings up the editor screen with the configuration file for the serial port and per-connection network settings.
Using the Terminal Configurator Configuration File Format The configuration file format is broken down into sections that define a particular grouping of options. Each section contains at the top a section header which is a string of text surrounded by square brackets: [ ] (the section title). After each section header, there is a list of entries containing equal signs. The text before the equal sign is a key and the text after the equal sign is the value.
Using the Terminal Configurator [bridge] Bridge provides variables that are common to all radios. Bridge affects the behavior of radios. AP refresh period. Periodically an Ethernet Adapter pings an Access Point. The AP Refresh Period is the time, in units of seconds, between pings. The default for this value is 60 (which should be left at this default). If this default is changed, there is a chance that the Access Point will not find the Ethernet Adapter unit on the network.
Using the Terminal Configurator [software] The [software] section is used to control the receiving and sending of bytes over the serial port. Proper setting of these values can significantly enhance the efficiency of data transmission because the radio is “packet based” and the UART is “stream based.” Stream based data means that the data is transmitted and received one byte at a time, without any mechanism to separate chunks of data from other chunks of data.
Using the Terminal Configurator transmitted immediately. Conversely, if another character is received before this time-out, the timer is restarted from the beginning. The range for this value is from 10 to 65536 milliseconds, though it will always round up to the nearest tens of milliseconds. For instance, setting the time-out to 55 will mean the Ethernet Adapter will wait for 60 milliseconds before giving up and transmitting the data. • delimiters.
Using the Terminal Configurator [flow control] The Ethernet Adapter supports the following six flow control options: Recognize RTS, Generate CTS, Recognize DTR, Generate DSR, Recognize XON/XOFF, and Generate XON/XOFF. It also supports the original RS-232 specification for flow control where CTS is generated only when RTS is asserted. These options are explained below.
Using the Terminal Configurator immediately; otherwise, all of the data thereafter would be lost.) The host computer, however, would have to ask permission from the modem to send data. The host would do this by asserting the RTS line. The modem would see this, and check to see if it were ready to accept data. If so, it would then assert the CTS line, thus giving it permission. Once the host computer finished sending the data, it would drop the RTS line and the modem would subsequently drop the CTS line.
Using the Terminal Configurator CTS and DSR are output lines. When set to “negate” or “assert,” they will output a continuous digital value. The value “negate” outputs a logic 1, or “mark” which is electrically negative. This is also the state seen on an RS-232 connector when the cable is unplugged. The value “assert” outputs a logic 0, or “space” which is electrically positive.
Using the Terminal Configurator [telnet] The following section specifies the operating parameters for the Telnet protocol. A-14 • connect. This entry dictates what kind of prompt is seen on the serial port output. The two choices available are: wait for keystroke and command prompt. The default command prompt will give a prompt "telnet>", much like the Telnet software prompt on a UNIX system. From this prompt, using the “open” command will then connect the device to a particular machine.
Using the Terminal Configurator Network Bindings This section describes the meaning behind each of the entries that describe network binding. [rmpbind] This binding can be used for both the passthrough protocol and for the I/O control socket setting. • protocol. This example uses the RMP protocol so the value of this entry is “rmp.” RMP binding options are described below. If you wish to use the TCP/IP protocol, skip to the next example. • source address.
Using the Terminal Configurator • transmit retry interval. When attempting additional transmit attempts as specified with “transmit try count” above, it can be useful to additionally specify how long to wait between attempts. This setting determines the time period for retransmission attempts. The value is specified in 1/100ths of a second, so that 100 means 1 second. The maximum value is 65000. The default value is 100.
Using the Terminal Configurator • serial connect data. The format is the same as in socket connect data. This causes data to be written to the UART once a connection is successful. • serial disconnect data. This causes data to be written to the UART when the network connection has been closed. This data is appended to any data already in progress. The closing of the socket will not cancel UART transmission of any data already received over the socket.
Using the Terminal Configurator [encryption] This value uses the RC4 algorithm as defined in the IEEE Wired Equivalent Privacy (WEP) standard to encrypt data. Enter up to four keys. The standard RoamAbout PC Card supports the 40-bit encryption only. The standard 40bit encryption uses a 5-character key (or a 10 digit hexadecimal digits). The 128-bit encryption uses a 13-character key (or 26 hexadecimal digits) and supports both 40-bit and 128-bit encryption.
Using the Terminal Configurator [ip] The following sections sets the configuration of the IP protocol. • ip address. This is the IP address that will be used by other computers to communicate with a particular Ethernet Adapter. • netmask. This is a value that, when logical ANDed with the IP address, specifies the range of IP addresses within the local network. • broadcast. In the local network, this is the IP address that is used to refer to all computers simultaneously.
Appendix B Problem Solving This appendix contains problem solving information for the RoamAbout Ethernet Adapter. If your Ethernet Adapter is not operating properly, please make sure the Ethernet Adapter is running the latest firmware, and use this guide before contacting Technical Support. If you receive an error message in your log file, save the error in the SAVE CONFIGURATION file. Table B-1 lists problem diagnostics and Table B-2 lists event log errors.
Table B-1: Problem Diagnosis B-2 Situation Problem Steps to take The power light is off or the power light is blinking. The Ethernet Adapter is not receiving power properly. Verify that all physical connections are securely in place. The power light is on steady and the status light is on. Configuration or software alert condition Check the System Event Log to determine the cause, and refer to the following Event Log Error Table.
Situation Problem Steps to take The Ethernet Adapter is connected to an Ethernet cable, but the Ethernet Link Light is not lit. Invalid connection to Ethernet • Verify that both ends of the cable are plugged in securely. • If the Ethernet Adapter is attached to a hub, a crossover Ethernet cable must be used. If the Ethernet Adapter is attached directly to an Ethernet device (i.e., a PC or Ethernet printer), it must be a straight-through cable. Verify that you are using the correct cable.
Table B-2: Event Log Error Table All entries in the event log are preceded by a number. This number is a timestamp used by Technical Support, but is not relevant to looking up items in this table. Error Code Problem Steps to take Section named yyyy in configuration file named xxxx was missing. • Save your current configuration (if applicable). • Reset the Ethernet Adapter units configuration to Factory Defaults. • Reset the Ethernet Adapter. • Restore configuration (if applicable).

If any of these steps succeed, you do not have to perform the rest of the steps. 1) Reset the Ethernet Adapter. Hardware Errors 2) Unplug the power, wait for approximately 30 seconds and then reapply power.
Appendix C Serial Line Configuration This appendix describes how to perform wireless serial line replacement, configure your Ethernet Adapter as a network serial port, and configure your Ethernet Adapter as a serial telnet client. Serial Line Replacement Two Ethernet Adapter’s are required to perform wireless serial line replacement. Serial line replacement can operate with the radio in either Infrastructure or Ad-hoc mode.
Serial Line Replacement To configure for the RMP Pipe protocol, perform the following steps: 1) Complete the Basic Radio Configuration instructions described in Chapter 4. NOTE If you are replacing a serial line or serial network with two or more Ethernet Adapter units without using an Access Point, ensure that your radio is using Ad-hoc mode. 2) Complete the General Serial Configuration described in Chapter 5. 3) Click on the Serial tab. 4) Select the Protocol tab.
Serial Line Replacement • Destination Address. This address tells the Ethernet Adapter where to send data received on the serial port. You may enter the RMP address of another Ethernet Adapter for direct serial line replacement. Other possible values are “dynamic” or “broadcast”. Entering “dynamic” causes data to be sent to the Ethernet Adapter from which the unit last received data.
Serial Line Replacement TCP Pipe TCP Pipe, like RMP Pipe, makes no changes to the serial data stream. TCP Pipe differs from RMP Pipe in that it creates two independent network connections for transmitted and received data. Using two connections allows each Ethernet Adapter to detect conditions when it has lost radio contact with the opposite unit, as can occur in environments with poor radio communication. In this configuration, each Ethernet Adapter unit simultaneously acts as a client and a server.
Network Serial Port Network Serial Port This section describes how to configure your Ethernet Adapter as a network serial port. Connection to a network serial port is accomplished over a TCP/IP socket connection. Any program that uses standard TCP/IP network sockets may be used to communicate with the serial port of the Ethernet Adapter. Once a socket is established to the Ethernet Adapter, any data written to the socket will be sent out the serial port of the Ethernet Adapter.
Network Serial Port TCP Listen Port Configuration Complete the configuration described in Network Serial Port Configuration, steps 1–4, and then perform the following steps: 1) Click on TCP Listen Port in the Protocol list. 2) Click on the Listen tab. 3) Type in the port number on which the Ethernet Adapter will listen for a connection. This is the port number that your program will use to connect to that Ethernet Adapter. The default is 4000.
Serial Telnet Client Serial Telnet Client This section describes how to configure your Ethernet Adapter as a serial telnet client. Telnet is a method to connect and remotely log-in to a host computer or network device. The host computer or device must be running a telnet server for this service to be available. Once the telnet session is established from the Ethernet Adapter, any data received by the serial port of the Ethernet Adapter is sent to the host.
Serial Telnet Client 4) Leave the Reconnect After Shutdown box checked to allow a new session after closing an active one. 5) Click on the Update and Reset Unit button. Command Prompt Connection Configuration This section describes the command prompt connection method for a serial telnet client. The command prompt connection method provides a “telnet prompt” to the serial terminal.
